"I am here to give it my best shot and hopefully add something positive to the place and earn a chance to realise my Olympic dream."
Cycling New Zealand said that while they have supported Kerby's switch, which has also received the blessing of Cycling Australia and cycling's ruling body the UCI, that he comes with no guarantees.
"Jordan is moving here of his own volition. We will incorporate him into our endurance group and evaluate his performances and how he fits into our group," said Cycling New Zealand High Performance Director, Martin Barras.
Kerby was part of the Australian pursuit squad that went 3m52s on two occasions while the best for New Zealand is 3:53. He also clocked 4:12 as an individual pursuiter to win the world title which is one of the five fastest times in history.
"Australia has massive depth in pursuiting and while we are pleased with the development of our young riders, and we have the potential of some others returning from the road, the reality is that we want the fastest possible team on the track in Tokyo," said Barras.
"If Jordan can do his talking on the track and can fit in with our team culture, then he will be a significant asset to the programme."
